The present invention relates to novel mono- or polynuclear melamine compounds and their use as dispersants for pigments and fillers in coating compositions, in particular in solvent-borne coating compositions. The mono- or polynuclear melamine compounds of the invention have at least one 2,4,6-triamino-1,3,5-triazine ring, wherein at least one amino groups of at least one of the 2,4,6-triamino-1,3,5-triazine rings of the mono- or polynuclear melamine compounds is of the formula A:NRR(A) where Ris H, CH(R)ORor R, Ris CH(R)O(A-O)&#x2014;R, where Ris H, C-C-alkyl or aryl; Ris H, C-C-alkyl or C-C-alkoxy-C-C-alkyl; Ris a hydrocarbon radical having from 1 to 40 carbon atoms; x is an integer from 2 to 500, having on average a value in the range from 2.5 to 400; A is an C-C-alkan-1,2-diyl radical.

Melamine-polyethers as dispersants in non-aqueous, liquid pigment compositions

What are described are compounds having two or more exovinylene cyclocarbonate units, wherein the exovinylene cyclocarbonate units are bonded to one another via at least one organic, siloxane-free connecting group which is not bonded directly to the exovinylene double bonds, excluding connecting groups formed by polymerization of (meth)acrylic monomers. The connecting group preferably has at least one acetal group. Also described are a process for preparing the compounds, two-component binders comprising the compounds, and uses of the compounds.
